New generators and compressors from Doosan
/Min. The Stage IIIB models are called 9/275, 9/305, 12/250, 17/240 and 21/220 to distinguish them from the predecessor Stage IIIA models in the same capacity range, the 9/270, 9/300, 12/235, 17/235 and 21/215.The compressors are powered by the Cummins QSL9 Stage IIIB engine using exhaust gas recirculation (EGR), diesel oxidation catalyst (DOC) and diesel particulate filter (DPF) after-treatment technologies.
The new models are designed to combine compact size with easy serviceability. Two units of the new 12/250 model can fit on a typical delivery truck and although smaller than its predecessor, the 12/250 compressor offers a higher flow: 25 m³/min compared to 23.5 m³/min previously.
The 12/250 compressor has a completely new control system with a full colour digital display. Manuals in electronic form are available on the display, and the WiFi interface allows for live streaming of data to operators or to the laptop, tablet computer or smartphone of service technicians. Several additional features such as multiple air outlets, a 110% bunded base, central drains and forklift slots have also been incorporated as standard in the 12/250 compressor.





The order covers a range of equipment from Doosan including the 7/31EG portable compressor generator, which is equipped with an integral 6.5 kVA generator, meeting a specific requirement on contracts for utilities such as gas, water, electricity and
